The function of cooling system of foam granulator

Foam granulating machine
The role of the cooling system
After the extruded strip leaves the machine head, the waste foam plastic should be cooled and shaped immediately, otherwise it will occur under the action of gravity. Deformation. The cooling method usually uses water cooling, and is divided into rapid cooling and slow cooling according to different water temperatures. Rapid cooling is direct cooling with cold water. Rapid cooling is beneficial to the shaping of plastic extruded cladding. However, for crystalline polymers, due to the sudden cooling, internal stress is likely to remain inside the extruded cladding structure, resulting in cracks during use. Generally, plastics The layer adopts rapid cooling. Slow cooling is to reduce the internal stress of the product by placing water of different temperatures in the cooling water tank in sections to gradually cool down the product and shape it.
Jilin Laoqiang Plastic Crusher Factory
is a professional manufacturer specializing in the production of foam granulators, mineral water bottle crushers, plastic crushers, plastic granulators, textile bag crushers, and granulators. According to relevant national departments, there are about 10,000 tons of waste plastics in our country that have not been recycled. If they are reused, they can control pollution and create huge economic benefits. It is a green environmental protection industry that benefits the country and the people. Modern economists call it Humanity's second mineral deposit. Processing these waste plastics requires labor-saving and energy-saving machinery and equipment
